Electrical Connector Contact Standoff for Reliable Socket Molding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As CPU socket form factors increase, the number of contacts and volume of the insulative base also rise, leading to inadequate formation of standoffs during the molding process due to a decreased volume ratio of standoffs to the insulative base.
Innovation Solution
The electrical connector features an insulative base with holes for mounting contacts, each contact having an upper contacting arm and a side portion with a standoff secured to it, ensuring proper positioning and formation of standoffs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number of contacts and volume of insulative base are increased to accommodate larger CPU socket form factors, then the capacity and functionality are improved, but the volume ratio of standoff to insulative base decreases, leading to inadequate standoff formation during molding
Solution Approach 1:
The patent divides the standoff formation process into two independent stages: first forming the standoff on the contact body, then molding the insulative base around it. This segmentation allows the standoff to be properly formed on smaller contacts without being compromised by the overall base size, resolving the contradiction between increasing contact quantity and maintaining standoff formation quality.
Solution Approach 2:
The standoff is formed on the contact body before the insulative base molding process begins. This preliminary action ensures that the standoff has adequate volume and proper formation regardless of the final base size, preventing short shots and other molding defects while allowing the base to scale to accommodate more contacts.
2Volume of stationary object
If the volume of insulative base is increased to support more contacts, then the structural capacity is improved, but the relative size of standoffs decreases, causing molding defects
Solution Approach 1:
The patent segments the manufacturing process into distinct stages where the standoff is formed independently on the contact before base molding. This allows the base volume to increase for capacity while the standoff volume remains adequate for reliable molding, eliminating the trade-off between base size and standoff formation reliability.
Solution Approach 2:
By forming the standoff on the contact body prior to insulative base molding, the patent ensures that the standoff achieves proper volume and structural integrity before being embedded in the base. This preliminary formation maintains molding reliability regardless of the final base volume.
